Just bought a 2008 A4 Cabriolet with 27,000+ miles. First of all brakes squeal horribly when stopping at low speeds, also just started noticing that when I have to make a sharp turn to the right there is a grinding sound in the front wheels. WTH???? I was told that the brakes squealing was the "type of pads" that are on it and something about metal flakes causing the sound because I don't drive it constantly. But what is this noise when I make sharp turns? It is still under warranty, so do I take it in or is this "normal" ? Excuse my ignorance but this is my first foreign car. Daddy always raised me as a Ford gal! LOL THanks for any input or help.
